It's possible the Xbox product page just revealed the Xbox Series X release date. At the bottom of the page is the Xbox Series X logo and the slogan "power your dreams". However, some regional variants of the site had the additional text "coming Thanksgiving 2020" underneath the slogan. An Xbox executive has reported the potential reveal as "inaccurately listed".

Of course they're trying to make it before Thanksgiving. But if they can't make it, it will be delayed until Christmas. so they are being careful in not giving any concrete date, because they don't know!
